C Command Table Format
These commands are from the C command above. All of these commands are
redundant, and are provided for users of existing Lasair II particle counters who
want to simplify their upgrade path. Some of these commands split internal
variables into several pieces. For instance “C 0” through “C 6” are used to set date
and time. Because of the variable split, unexpected results can be obtained if the
user is not careful with software coding. For instance, setting the date and time in
multiple parts has the possibility of time-rollover in-between settings. In other
words, if the Lasair II particle counter seconds rolls over from 59 to 0, then at a
minimum the minutes will also change, and if this occurs right after setting the
minutes, then the expected time will be wrong.
